'''Gerhard Chroust''' (born 23 April 1941) is an [[Austria]]n [[systems scientist]], and Professor Emeritus for [[Systems Engineering]] and [[Automation]] at the Institute of System Sciences at the [[Johannes Kepler University of Linz]], [[Austria]]. Chroust is an authority in the fields of formal [[programming languages]] and interdisciplinary [[information management]].

== Biography ==
Gerhard Chroust was born in 1941 in [[Vienna]], [[Austria]]. He started to study [[Communications-electronics]] in 1959 and received a M.A. from the [[Vienna University of Technology]] in 1964, a M.A. from the [[University of Pennsylvania]] in 1965, and a PhD. from the [[Vienna University of Technology]] in 1974.

Chroust started working at the Kepler University Linz and the Technical University Vienna in 1975 as Lecturer for [[Microprogramming]]. In 1980 he became Assistant Professor in Computer Science, and lectured "Dataflow Mechanisms", "Dataflow Mechanisms" and later "Software Development Process" at the Kepler University Linz, at the [[University of Klagenfurt]] and the Technical University of Vienna. From 1992 until 2007 he was Professor for 'Systems Engineering and Automation' at the Kepler University of Linz and Department Head of the Department (in 2004 transferred into an Institute) of Systems Engineering and Automation from 1992 until 2007.<ref>[http://www.icsci.net/profile%20of%20Gerhard%20Chroust.htm Ing. Dr. Gerhard Chroust, M.S.] at www.icsci.net. Retrieved 3 June 2008.</ref>

Chroust is Editor-in-Chief of the [[International Federation for Systems Research|IFSR]] Newsletter a.o. Furthermore he is Chairperson of the Editorial Board of the Book Series of the Austrian Computer Society (OCG), Editorial Board Member of several journals: The Journal of ''Microprocessors and Microsystems'' from 1976 until 1985, the ''IBM Programming Series'' from 1978 until 1990, the ''Computer Standards and Interfaces'' from 1992 until 2005, and
''[[Systems Research and Behavioral Science]]'' since 1994. In 1997 he was also on the Academic board of the [[International Encyclopedia of Systems and Cybernetics]]'', edited by [[Charles François (systems scientist)|Charles François]].

Further Chroust is organizationally active is as Secretary/Treasurer at the [[International Federation for Systems Research]], Vice-President of the Austrian Society of Cybernetic Studies and Advisor to Austrian Standards Committee.

== Work ==
The research interests of Gerhard Chroust are in the fields of [[Software Engineering]] (Representation and Enactment of Software Process Models, Quality and Improvement of Development Processes), [[Systems Science]] and Systemic Aspects of [[Engineering]], [[Emergence]], History of [[Computers]] and [[Information Technology]], and Human Aspects of [[Software Development]].

=== Cybernetics and Programming Languages ===
In 1964 Chroust wrote his Masters Thesis "Kybernetisches Modell: Muehlespiel Masters" about [[cybernetics]] and continued to investigate cybernetic machines for another four years.

From the study of Theorem Proving 1965-66 Chroust continued to study formal definition of [[Programming Languages]], whereby he developed the "[[Vienna Development Method|Vienna Definition Language]]". He started studying [[compiler theory]] and the evaluation of [[arithmetic expression]]s from 1967 until 1975.

In the 1970s Chroust continued to study parallelism and [[simulation]] from 1969 until 1972, [[microprogramming]] from 1975 until 1990 and [[compiler]] building from 1976 until 1982.

=== Software engineering and information engineering ===
In the 1980s the scope of Chrousts research turned towards [[Software Engineering]] and its environment, and towards [[Information Engineering]] in the 1990s. He had a special interest in [[software inspection]]s and [[Workflow]] management.

== Publications ==
Chroust has written, co-authored and edited a dozen books and over 400 articles, papers and other publications.<ref> [http://fodok.jku.at/fodok/fodokjsp/list_pers.jsp?von=&bis=&per_id=1007&suche=Abschicken&suche=Abschicken Gerhard Chroust] Full list of publications.
